Title: Engine torque fluctuation absorbing device
Inventor: IIDA KEIICHI
IPC: F02B61/00
Filed: 1994-05-09
Abstract: PURPOSE:To reduce the cost of the switching unit of an inverter and to reduce damges in an engine torque fluctuation absorbing device for absorbing engine torque fluctuations during idle operation. CONSTITUTION:When an A.C machine 2 directly connected to an engine 1 is driven by means of a power generator, a generated voltage is boosted by means of a boosting converter 16 so as to charge a battery 10. In the case of using an electric motor, a current from the battery 10 is converted into an alternate current by means of an inverter 5 and supplied to the A.C machine 2. A flow-rectifying circuit for rectifying a generated voltage is used as a thyristor flow-rectifying circuit 18 switched ON only during operation by means of the power generator. Since the thyristor fow-rectifying circuit 18 is switched OFF during operation by means of the electric motor, a part of current IB flowing from the battery 10 to the inverter 5 is prevented from flowing to a large capacity capacitor 17 on the input side of the boosting converter 16. A current flowing to a switching unit 6 is only an armature current to the A.C machine 2 and thus the capacity of the switching unit 6 can be made smaller in comparison with a conventional one.

Title: Optical monitoring device
Inventor: FUKUSHIMA NOBUHIRO
IPC: G02B6/42
Filed: 1993-05-24
Abstract: PURPOSE:To remove non-polarization dependence and to improve the reliability by equalizing the ratio of P polarization transmissivity to S polarization transmissivity of a filter plate to the ratio of S polarization reflectivity to P polarization reflectivity of a splitter plate. CONSTITUTION:A filter plate 10 is installed between a splitter plate 5 and a lens 6 and inclined by a prescribed angle to an optical axis. The prescribed angle is an incident angle at the time of designing the device so that the ratio of P polarization transmissivity to S polarization transmissivity of the filter plate 10 is equalized to the ratio of S polarization reflectivity to P polarization reflectivity of the splitter plate 5. Thus, most of the emitted light beams of an optical fiber 1 on the input side is transmitted through the splitter plate 5 and transferred to an optical fiber 2 on the output side. On the other hand, a part of the emitted light beams of the optical fiber 1 on the input side is reflected by the splitter plate 5, the greater part of the reflected light beams is transmitted through the filter plate 10, reaches a lens 6, is converged by the lens 6, projected on the light receiving surface of a photodetector 7 and becomes an electrical output. At this time, the polarization dependence of the reflected beam of the splitter plate 5 is compensated by the filter plate 10 and the polarization dependence is almost canceled.
